title: Microbiologic oxidation of estratrienes and estratetraenes by Streptomyces roseochromogenes ATCC 13400.
abstract: Incubation of estrone (1a) with Streptomyces roseochromogenes ATCC 13400 yielded a mixture of 3,16 alpha-dihydroxyestra-1,3,5(10)-trien-17-one (3a) and 3,17 beta-dihydroxyestra-1,3,5(10)-trien-16-one (4a). Transformation of 3-methoxyestra-1,3,5(10)-trien-17-one (1b), 3-hydroxyestra-1,3,5(10),9(11)-tetraen-17-one (2a), and 3-methoxyestra-1,3,5(10),9(11)-tetraen-17-one (2b) with the same microorganism gave the corresponding mixtures of 16 alpha-hydroxy-17-ketones and 17 beta-hydroxy-16-ketones (3b and 4b, 6a and 7a, 6b and 7b, respectively). In addition, in these three last experiments, the 16 beta-17 beta-dihydroxy derivatives 5b, 8a, and 8b, respectively, were also isolated. The complete assignments of the 13C nuclear magnetic resonance spectra of these compounds are given.
